  U.S. Army Pursues Alternatives To GPS

  Jen DiMascio In its attempt to ensure that soldiers have access to GPS-like information, even when access to those U.S. Air Force satellites may be compromised, the U.S. Army is in the process of fielding an alternative system on certain ground vehicles. The Army began fielding the first iteration of the Mounted Assured Positioning, Navigation and Timing System (MAPS), an anti-jam GPS alternative, on General Dynamics Stryker vehicles in the 2nd Cavalry Regiment this year. The service will field 300 such systems to the 2nd Cav this year, according to Willie Nelson, director of the Army's Assured Positioning, Navigation and Timing Cross Functional Team. Thousands are supposed to be installed into vehicles in U.S. European Command by 2028. On Oct. 15, the U.S. Army announced it had chosen Collins Aerospace to provide a next-generation MAPS for manned ground vehicles. Collins will make MAPS Gen II, systems that will be evaluated for a year and potentially be fielded to 8,000 additional vehicles. The Collins Aerospace system combines the NavHub-100 navigation system and Digital GPS Anti-jam Receiver-100. The system adds a military code capability and modernized signal tracking to improve reliability and integrity, Collins says. The MAPS program is part of the U.S. Army's focus on modernization. But it is also a response to a request from commanders in Europe and Korea, according to Gen. John Murray, commander of Army Futures Command. The Army maintains that its effort to look for alternate means of positioning, navigation and timing is aligned with the U.S. Air Force's plans for GPS satellites. Asked about the threat from Russia, Brig Gen. Robert Collins, program executive officer for intelligence, electronic warfare and sensors, said the U.S. needs confidence not just in the ability of U.S. assets to withstand jamming attacks but to be able to fend off spoofing efforts as well. “The electromagnetic spectrum is becoming contested and people are operating in that space,” Collins said. “We recognize that our traditional GPS today is not where we need it to be from a survivability perspective. So we have looked at how to make it more hardened.” Along with those efforts, the Army has also planned an industry day for Oct. 29-31, as it seeks new inertial measurement unit and timing technologies. https://aviationweek.com/defense/us-army-pursues-alternatives-gps

  Hiding in plain sight: Warfare in the electromagnetic spectrum

  Most weapons systems---radios, ships, tanks, airplanes, drones, satellites, and rockets---depend on the electromagnetic spectrum to operate.
